Chapter 1 System Description
Chapter 1 System Description 1.1 Overview of the Product 1.1.1 Product Position The U-SYS iGateway Bill (hereinafter referred to as the iGWB) is a large-capacity billing gateway developed by Huawei. With advanced software and hardware techniques, the iGWB provides powerful CDR storage and conversion capabilities and supports the interconnection with a billing center through File Transfer Protocol (FTP) or File Transfer Access Management protocol (FTAM). The iGWB cooperates with the U-SYS SoftX3000 SoftSwitch System (hereinafter referred to as the SoftX3000), and provides a large-capacity CDR storage medium and billing interface for the SoftX3000.
1.1.2 System Applications The SoftX3000 is the core of the Next Generation Network (NGN) and resides at the network control layer of the NGN. The SoftX3000 provides the functions of call control and connection management of voice, data, and multimedia services based on Internet Protocol (IP) packet network. For each call, the SoftX3000 must perform the charging processing in addition to call control, media gateway access control, resource allocation, protocol processing, routing, and authentication. In other words, the SoftX3000 must record the call related information, such as the calling number, called number, answer time, and on-hook time, in a particular format. The charging tickets (also named original CDRs) generated by the SoftX3000 are buffered in the memory (usually called CDR pool) of its main processing unit. Limited by the capacity and security of the CDR pool, however, the original CDRs stored in the CDR pool must be transferred to a reliable storage medium in time. In addition, the contents and formats of the original CDRs are different from those required by the billing center, the CDR files must be pre-processed before being transmitted to the billing center. The iGWB is a gateway-like device placed between the SoftX3000 and the billing center, used to implement the CDR receiving, pre-processing, buffering, and billing interfacing functions. Figure 1-1 shows the position of the iGWB in system networking.

Figure 1-1 Position of iGWB in system networking As shown in Figure 1-1, the external devices taking part in the iGWB networking model include SoftSwitch system (SoftX3000), billing center, and operation & maintenance system.
I. SoftSwitch system SoftX3000 is responsible for call setup and control, producing original CDRs and storing them in its CDR pool temporarily. The iGWB server is connected to the SoftSwitch system through a separate network adapter, and receives the original CDRs from the SoftSwitch system.
II. Billing center Generally, online billing is adopted between the SoftX3000 and the billing center. In this case, it is a basic function of the iGWB to provide a network interface to the billing center. The CDR collector, a component of the billing center, has direct communication with the iGWB. The CDR collector and the iGWB are interconnected through Wide Area Network (WAN), and communicate with each other through FTP or FTAM. In the case of FTP, the iGWB acts as the server, and the CDR collector acts as the client. In the case of FTAM, the iGWB acts as the responder, and the CDR collector acts as the initiator in a way similar to FTP communication. The iGWB provides a separate network adapter for communication with the billing center.
III. Network management system and CDR console The iGWB is one of the devices managed by the network management system (NMS), and thus needs to provide a network interface to the NMS. The iGWB includes server and client. The iGWB client is managed by the NMS. Typically, it is required to configure a computer in the equipment room to function as a local maintenance console of the iGWB. A remote maintenance console can be configured as required. The iGWB provides a separate network adapter for communication with the NMS.

Chapter 1 System Description
1.1.3 Product Features I. High reliability 1)
Dual-system
Because of the special position of the billing system in networking, high reliability of the iGWB is demanded. To achieve that, the iGWB adopts a dual-system design in both hardware and software. In addition, the iGWB provides an automatic switchover protection mechanism between the dual systems to ensure the operation reliability and service continuity. 2)
Hard disk sub-system adopting redundant arrays of inexpensive disks (RAID) mode
Based on the experience of using server and mini computer, it is known that hard disk sub-system is prone to errors and failures. Therefore, the iGWB adopts RAID5 plus HotSpare. The purpose is to ensure that data will not be lost in the event of a fault occurring to one of the hard disks. 3)
Network backup
The iGWB can automatically back up CDR files to another server through WAN or LAN, to further improve the data security. 4)
Software auto-startup and restart after exit
A monitor module is designed in the software. The monitor module can automatically start up the iGWB in case of a power failure. The purpose is to ensure the normal running of the system when unattended.
II. Multi-access The iGWB can receive and process CDRs in different formats, for example, CDRs generated by a mobile system or fixed network system. The CDRs in different formats are stored separately and provided respectively to the billing center.
III. Flexible CDR format conversion The charging system of telecom carriers might have special requirements for CDR format. For example, they might need the iGWB to convert an original CDR in a binary format to a final CDR in another format such as text format or Abstract Syntax Notation One (ASN.1) format and abstract particular fields from an original CDR to generate a new CDR for the billing center. The iGWB provides flexible CDR format configuration and conversion functions to meet the diversified requirements of telecom carriers.

User Manual U-SYS iGateway Bill
Chapter 1 System Description
IV. Large capacity The available capacity of the hard disks configured in the iGWB determines its CDR buffering capability. With greater CDR buffering capability, the iGWB can store more CDRs on itself and archive fewer CDRs in the billing center, which enhances the security of CDRs. Currently, the hard disks configured in the iGWB provide a sufficient valid capacity to store the CDRs that are generated by the SoftX3000 in at least seven days in the case of maximum subscriber quantity. In addition, the iGWB is scalable in hard disk capacity.
1.2 Hardware Structure 1.2.1 Hardware Configurations In the SoftX3000, the iGWB and the basic service processing frame are configured in the same cabinet (integrated configuration cabinet). The related hardware components include active and standby iGWB servers, core Local Area Network (LAN) Switches, and an integrated converter, as shown in Figure 1-2.

Chapter 1 System Description
I. iGWB server The iGWB server is the core device of the iGWB system and adopts a dual-system design. Currently, two IBM X343 servers are employed. (Because server might be updated, the server module might be different from the actually delivered server model.) Each server provides four network adapters: two for communication with the SoftX3000, one for the billing center, and one for the NMS. In addition, the iGWB server has a built-in hard disk array. The iGWB server communicates with the SoftX3000 to implement CDR storage, format conversion, and pre-processing functions.
II. Integrated converter The active iGWB, the standby iGWB, and a back administration module (BAM) are configured in the integrated configuration cabinet. An integrated converter is thus configured in the cabinet, used to achieve operation control and switch of input and output devices, such as liquid crystal display (LCD), keyboard, and mouse.
III. LAN Switch LAN Switch is the communication channel between the iGWB and the SoftX3000. Generally, Huawei’s Quidway series products are selected for this purpose. Two LAN Switches are configured in the integrated configuration cabinet.
1.2.2 Functional Principles The iGWB adopts a dual-system design. Two servers are operating in the active and standby mode. Heartbeat link is set up between the servers. Handshake messages are exchanged between them for each server to monitor the operating status of the other. Whenever the active server becomes faulty, the standby server automatically becomes active. The purpose is to ensure the continuity of the provided services. In addition, each server provides network adapters for communication with the SoftSwitch, the billing center, and the NMS. Consequently, the system has a dual-plane structure, which further improves the reliability of the system. Figure 1-3 illustrates the operating environments of the iGWB.

Similarly, network adapters 1 of the active and standby iGWB servers must also be set with the same virtual IP address, which is in the same network segment as the standby plane of the SoftX3000. The virtual IP addresses are achieved by software configuration.
III. Communication with the billing center The iGWB server communicates with the billing center by using network adapter 3 for the billing center to collect CDRs. The communication protocol can be FTP or FTAM. Normally, the billing center simultaneously logs in to the active and standby iGWB servers. The active and standby iGWB servers provide different IP addresses to the billing center.
IV. Communication with the bill console and NMS Network adapter 2 is used for connection between the NMS and the bill console, providing a man-machine interface. In addition, network adapter 2 acts as the first heartbeat path between the active and standby iGWB servers. Network adapters 2 of the active and standby iGWB servers must be set with the same virtual IP address, which is in the same network segment as the CDR console (NMS). The virtual IP address is achieved by software configuration. For more information, refer to Chapter 2 “System Installation”.
V. Heartbeat paths Heartbeat paths are configured between the active and standby iGWB servers to exchange handshake messages. With the heartbeat paths, each iGWB server can monitor the operating status of the other and back up the status for future switchover usage. The status backed up includes CDR sequence number, front disk state, back disk state, and so on. The system provides two heartbeat paths, which are in the “private network” inside the system. The first heartbeat path is the LAN that is formed by network adapters 2. The second heartbeat path passes through serial ports. When the first heartbeat path is broken, the iGWB servers use the second heartbeat path for communication.
1.2.3 Configuration Relationship with Other Devices The following serving devices need be configured to ensure the normal running of the iGWB and facilitate maintenance.

User Manual U-SYS iGateway Bill
Chapter 1 System Description
I. Power supply The power distribution box in the integrated management cabinet supplies power for the iGWB. The nominal voltage is –48 VDC.
II. Integrated converter The active and standby iGWB servers are connected to the integrated converter through C2T line. The integrated converter achieves input/output control and other operations on the servers.
III. Client The iGWB also includes a computer as the client. The computer must be installed in the same LAN as network adapter 2 of the iGWB server. The client is used for device debugging, CDR browse, CDR query, and routine maintenance purposes.
1.3 Software Structure 1.3.1 Overall Software Structure The iGWB is a multi-process and multi-threaded system in the client/server mode. The iGWB software is designed to be several thread modules based on independent services. The thread modules that have the closest relationship to a particular service function are incorporated to be a specific process. In this way, the software is structured in multi-process and multi-threaded manners. Client/server mode is employed for communication between the processes. In other words, a particular process is the kernel, and the other processes act as sub-processes. The kernel process schedule and monitor the service sub-processes. Figure 1-4 illustrates the overall structure of the iGWB software.

Chapter 1 System Description
1.3.2 Service Processes As shown in Figure 1-4, the iGWB server is composed of a kernel process, a dual-system process, an access point process, and an operation and maintenance process. Each process contains several service thread modules that are relatively independent of each other.
I. Kernel process The kernel process is the core of the whole software. It acts as the Transmission Control Protocol/Internet Protocol (TCP/IP) server for the other processes. It is responsible for starting, stopping, and monitoring the access point process and the operation and maintenance process. This process is composed of a dual-system monitor module and a dual-system interface module.
II. Access point process The access point process incorporates the main service functions of the iGWB, including CDR reception, CDR processing, and CDR storage. The service functions are integrated to be a network module, a front disk module, a CDR processing module, and a back disk module. The four modules constitute a CDR processing flow, in which the service log is uni-directional and can be cut down. See Figure 1-5. (The arrows stand for the transmission directions of the CDR data.)

III. Operation and maintenance process The operation and maintenance process integrates the operability and maintainability functions of the iGWB. In terms of functionality, the incorporated service modules include a log module, a backup module, a CDR browse and query module, a man-machine language (MML) server module, a performance module, and an alarm module. The modules are relatively independent of each other.
IV. Dual-system process The design of the iGWB aims at the cross-platform dual systems. The dual-system design greatly varies with different platforms. Consequently, the dual-system process is used to mask the details of the dual-system functionality at different platforms. The dual-system process enables the processes interacting with it to ignore the differences of the platforms. This process has only one service module—a dual-system management module. Each of the preceding four processes has a management module and a message transfer module. The management module manages and schedules the various

modules inside the process. The message transfer module is responsible for communication and message transfer between the processes.
1.4 System Functions The iGWB system provides two categories of functions: system service, and operation and maintenance.
1.4.1 Service Functions I. CDR processing function The iGWB system sorts the original CDRs as required. The different types of CDRs can be sorted to different storage directories in accordance with the pre-defined sorting conditions, for example, sorting by CDR type.
II. Flexible billing interface The iGWB system can communicate with the billing center through FTP or FTAM. The iGWB system supports configuring CDR file name, file size, and file generation time. The iGWB system supports flexibly converting CDR format.
III. Reliable dual-system function The iGWB system supports automatic switchover and manual switchover of the dual systems. The iGWB system supports auxiliary upgrade.

2.2.2 Installing Server Cables I. Connecting power cables The power input to the IBM x343 server is –48 VDC. Dual redundant power supplies are adopted, and thus the server can keep running normally when only one power supply is available. When connecting power cables, note that the positive pole of the power terminal of the server should be connected to the grounding terminal of –48 VDC power supply, and that the negative pole should be connected to the “–48V” terminal of –48 VDC power supply.
II. Connecting network cables The IBM x343 server provides four network ports. The network ports are numbered as shown in Table 2-2 for description purposes. Network cables must be strictly installed based on the correspondence. Table 2-2 Numbering plan of server network adapters Position

IV. Connecting C2T cables C2T cables are used to connect the servers with display, keyboard, and mouse. To save space, two iGWB servers and the BAM server will share one set of display, keyboard, and mouse, which are switched by the integrated converter. The servers are connected to the KVM/LCD converter through C2T cables. 2-6
User Manual U-SYS iGateway Bill
Chapter 2 System Installation
One end of the C2T cable is connected to the corresponding port of the server. The other end of the C2T cable is connected to the correct channel port of the KVM/LCD converter.
V. Connecting disk array cables The disk array is configured in IBM x343 server with ten hard disks. The disk array is divided into two parts, each of which provides a signal cable. Connect the left disk array to iGWB0 and the right disk array to iGWB1.
VI. Binding cables The iGWB related cables should be bound with the other cables in the integrated configuration cabinet. For details, refer to U-SYS SoftX3000 SoftSwitch System Hardware Installation Manual. If the installed softswitch system is not the SoftX3000, read the related manuals for installation.
2.3 Installing Operating System The installation steps for the operating system of the active and standby iGWBs are the same. The following presents the installation steps of the active one and provides the specific settings of the standby one when different. Before the installation of Windows 2000, conduct the RAID configuration of the server. The built-in hard disk array of the iGWB server should be set to be “RAID5 + HostSpare” (3+1+1) mode. Installation of Windows 2000 Server requires two CDs: ServeRAID Support CD for RAID5 setting and Windows 2000 Server CD (with Windows 2000 Service Pack 4.0 contained) for Windows 2000 Server installation.
2.3.1 Setting iGWB Hard Disk to “RAID5 + HostSpare” Mode
Caution: Re-setting of the RAID5 mode of the hard disks will cause all data on the disks lost. Be careful to perform this operation.
2-7
User Manual U-SYS iGateway Bill
Chapter 2 System Installation
The hard disks of the iGWB server employ the “RAID5 + HostSpare” redundant and error tolerance techniques for data security purposes. RAID5 is a disk-striping strategy with a dedicated check disk. Data is allocated on several disks to improve the read/write speed. Check data is also allocated on several disks instead of being stored on a dedicated check disk. When one of the disks becomes faulty, the controller can restore or create the lost data from other disks without influence on the availability of the data. RAID5 requires a minimum of three disks. The availability ratio of the disk space is about (N–1)/N, in which N is the number of the disks in the hard disk array. Compared with the “RAID5” mode, the “RAID5 + HostSpare” mode adds one disk as the hot spare disk. When the iGWB uses the IBM server, the hard disk array is usually configured (with ten hard disks). DIP switch of the hard disk array can be set so that the active and standby servers manage five hard disks respectively. (Four hard disks are set to the RAID5 mode and the left one is configured to hot spare.) Set the first bit of the DIP switch SW4 of the hard disk array to “ON”, and retain the factory settings of the other switches.
Note: The hard disks of the iGWB have been set to the RAID5 mode before the delivery. Confirm the RAID5 mode at the site.
The IBM server provides a dedicated tool, ServeRAID Manager, to manage and configure ServeRAID. The graphical interface of the ServeRAID Manager is shown in Figure 2-6.

The RAID adapter must have been installed before the hard disks are partitioned; otherwise, the hard disks in the array cannot be identified.
2.3.6 Partitioning iGWB Hard Disk In consideration of the requirement of the iGWB server software on hark disk partitioning, the iGWB hard disks need be divided into three partitions. All the partitions should use the NTFS file system. It is recommended to set the letters of the partitions (logical drives) to “C”, “D”, and “E”, and the CD-ROM drive to “F”. To ensure data security, the size of the partitions of the iGWB hard disks should be set to the following: z
Partition C: 8 GB, used to install the operating system and the iGWB server software.
Caution: 8 GB is allocated to drive C in the hard disk of the server (about 34 GB), and the left space (26 GB) is reserved for future use.
z
Partition D: 105 GB, used to store the original bills, log files, and status files.
z
Partition E: 105 GB, used to store the final bills and backup files.
According to the preceding requirements, you can use the disk management tool provided by Windows 2000 Server to partition the iGWB hard disks and set drive letters. To achieve that, proceed as follows:

2.3.7 Setting IP Address for iGWB Network Adapter The network ports are initially set to dynamically obtain IP addresses. You can assign an IP address for each network adapter according to the actual application. Setting of IP address depends on the actual situations at the site and the software installed. It is recommended to assign the following IP addresses for the network adapters as shown in Table 2-3. Table 2-3 Assignment of IP addresses Network adapter identifier
Connected device
IP address for active iGWB
IP address for standby iGWB
Virtual IP address
Netcard0 to 0#LAN Switch

The recommendations are the default values in the igwb.ini file. The IP addresses of the iGWB network adapters can also be differently planned with the following rules: z
The dual-system iGWB communicates with outside through the virtual IP address rather than the actual IP address of a network adapter.
z
The IP address of the network adapter to the billing center must be negotiated with the billing center.
z
The IP addresses must be consistent with those set in the igwb.ini file.

II. Checking and Reidentifying Network Adapters The system also automatically searches for the network adapters and marks Local Area Connection, Local Area Connection 1, Local Area Connection 2, and Local Area Connection 3 orderly when installing the driver for iGWB network adapters. The number sequence may be different from the actual physical numbering. Before configuring the IP addresses of iGWB network adapters. You must confirm the physical relationship between network adapters according to Figure 2-50, and identify network adapters again. In this way, you can identify network adapters correctly and prevent misoperations. To achieve this purpose, proceed as follows: Plug out all network cables connecting to iGWB network adapters. Then, the Local Area Connection icons for all network adapter change into
(not activated).
Connect the corresponding network cable to the port of network adapter 3, and ensure that the Core LAN Switch 0 connecting with network adapter 3 is started. In this case, the “Local Area Connection” icon of one network adapter changes into (activated). Right-click the activated icon, and select [Rename] from the shortcut menu to rename the network adapter to “Net Adapter 3 to Core LAN Switch 0”. Identify the other three network adapters in the same way. It is recommended to name network adapter 1, 2 and 3 to Core LAN Switch 1, Office LAN and Billing System respectively.
III. Setting IP Address of Network Adapter 0 To assign an IP address, for example, 130.1.2.1 to the Network Adapter 0 to Core LAN Switch 0, proceed as follows. At the Windows 2000 Server desktop, right-click the My Network Places icon. Select [Properties]. 1)
In the displayed windows, right-click [Local Area Connection]. Select [Properties].

Select [Start/Run]. In the displayed dialog box, enter “regedit” and press . The [Registry Editor] window is displayed.
2)
Select
[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows
NT/CurrentVersion/Winlogon] in the navigation tree. Select [Edit/New/String Value] at the menu bar. Create a string of characters “AutoAdminLogon”. Double-click the string. Assign “1” to it to enable the automatic logon. 3)
Create a string of characters “DefaultUserName”. Double-click the string. Enter the username for logon by default, for example, “Administrator”.
4)
Create a string of characters “DefaultPassWord”. Double-click the string. Enter the password for logon by default. If those values exist, double-click and edit them.
Caution: If no password is set, the automatic logon will fail.
After the setting, close the registry. Now, the installation of the operating system of the server is completed.
2.4 Installing Billing Interface The iGWB supports two types of online billing interfaces: FTP and FTAM. It is unnecessary to install both of them at the same time. In fact, only one set of interfaces is enough according to the design requirements. Because the FTP server software is installed while Windows 2000 is installed, it is only required to configure the FTP server in this section. If the FTAM interface is used, the FTAM software must be installed and configured. When the FTP interface is used, the iGWB serves as the FTP server, and the billing center as the FTP client. When the FTAM interface is used, the iGWB serves as the FTAM responder, and the billing center as the FTAM initiator.

2.4.1 Installing FTAM Protocol UTS-FTAM 7.3 developed by Vertel is adopted as the FTAM protocol in the iGWB. It includes two sets of software: protocol stack software (UTS-NetLink 5.2) and application layer software (UTS-FTAM 7.2).
I. Applying for license UTS-NetLink 5.2 and UTS-FTAM 7.2 use separate installation CDs and independent licenses. Each license is bound with the physical address (MAC address) of the corresponding network adapter. It might take 24 hours to apply for the licenses; therefore, application must be made in advance. 1)
On each of the active and standby iGWB servers, run the command C:\>ipconfig /all to obtain the MAC address of the network adapter from the active/standby iGWB server to the billing center.
2)
Send the MAC addresses (both of the servers must have their respective license) to
[email protected]. The licenses will be obtained in one day.
Caution: Do not send two or more MAC addresses of one server to the supplier, because it means two or more licenses are bought for the same server.
3)
Receive the license e-mail from Vertel. The following is a license sample of Vertel:
SERVER snaylm 00065B24A878 VENDOR vertellm INCREMENT UTSftam vertellm 1.9999 30-jul-2002 4 F3A2A3EB13BA ck=129 \ SN=200003150434

3)
If you are prompted to press after the iGWB restarts, the automatic logon function of Windows 2000 Server is set unsuccessfully. Re-setting is needed.
2.8.3 Checking Server Software I. Working state 1)
Switch the input and output to the active server. Check the bulb in the status area. If the bulb is lit, it indicates that the active server is configured correctly and operating well.
2)
Manually switch over the iGWB servers. Switch the input and output to the standby server. Check the bulb in the status area. If the bulb is lit in five minutes, it indicates that the standby server is configured correctly. Switch the input and output to the active server. Check the bulb of the active server. If the bulb is not lit, it indicates that the parameters of the active and standby servers are all set correctly and both servers are operating well.
3)
If a running status exception happens during the start process, check the trace files in C:\iGWB\trace, and correct the configuration file accordingly. If the system is still abnormal after configuration correction, it is recommenced to re-install the iGWB server software. For the analysis and modification of the trace files, refer to Chapter 4 “System Maintenance”.

4.3 Software Upgrade 4.3.1 Overview of Software Upgrade There are two types of software upgrade of the iGWB, namely ordinary upgrade and special upgrade. An ordinary upgrade does not change the existing directory structure or program structure of the original version. The ordinary upgrade does not influence any data regarding the original version, either. After the ordinary upgrade, the system continues to operate from the status of the original version, and the sequence number of bill file is incremented continuously. A special upgrade causes the change of the interface between the iGWB and the SoftX3000 or between the iGWB and the billing center. The change of the interface
4-4
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
between the iGWB and the SoftX3000 refers to the change of the format for the charging tickets. Consequently, the length of a charging ticket is changed. The change of the interface between the iGWB and the billing center refers to the change of the format for the bill files. In a special upgrade, the igwb.ini file must be set again. If the system status file is not deleted, however, the sequence number of bill file will be incremented continuously.
Caution: z
Before a special upgrade, ensure that the billing center can normally fetch bills from the iGWB and all the bills have been fetched by the billing center. Otherwise, bills might be lost.
z
The status file of the system is stored on E:\Statusfile by default. The backup of the status file is stored on E:\Statusfileb. In a special upgrade, read the installation guide to determine whether to delete the status file.

4.4 Troubleshooting 4.4.1 Introduction to Fault Positioning Information Fault positioning information about the iGWB falls into the following types: z
Device maintenance and fault positioning interfaces provided in the design of the iGWB software, such as trace information, parameter configurations, and log.
z
Fault positioning measures provided by the operating system, such as ifconfig/ipconfig, netstat, and ping.
4-7
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
I. Fault positioning information provided by the iGWB software 1)
Trace information
Trace information plays an important role in positioning a fault. Each piece of trace information is expressed in the following format: Trace generation time Module number writing the trace
Trace contents
Trace records are significant debugging information for the running of the system. Trace is not equal to abnormality. Usually a large number of trace records are generated when the system is started or shut down. A few trace records are generated during the system is operating normally. The iGWB application has four types of processes, namely dual-system process (cls_proc.exe), kernel process (knl_proc.exe), access point process (ap_proc.exe), and operation and maintenance process (om_proc.exe). In the actual running, the dual-system process, kernel process, and operation and maintenance process have only one respective process instance, but the access point process can start one or more process instances depending on the parameter configurations. Each process instance of the iGWB creates a trace file. The following is the format for naming trace files of the dual-system process, kernel process, and operation and maintenance process: ProcessName_trace.txt For example, the trace file of the operation and maintenance process is named om_proc_trace.txt. Because the access point process might have several process instances, the access point ID is added in the trace file name for identification purposes. The specific format is as follows: ap_procAccessPointID_trace.txt For example, the trace file of the first access point is named ap_proc1_trace.txt. In addition, the size of each trace file is limited to 6 MB. If the trace file exceeds this limit, the application changes its extension from “txt” to “tmp”, and then creates a new trace file. All trace files of the iGWB are stored in the trace folder on the installation directory (C:\igwb by default). 2)
Configuration information
Because a large number of faults are caused by parameter configuration errors, it is recommended to analyze both parameter configuration files and trace information. Configuration information of the iGWB includes parameter configuration information and bill format configuration information. The parameter configuration information is
4-8
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
stored in the \config\ini\igwb.ini file on the installation directory. Currently, that is the only parameter configuration file. The bill format configuration information is stored in the \config\format on the installation directory. 3)
Bill files
To remove a bill exception of the iGWB, analyze the original bill file and the final bill file. The original bill files and the final bill files of the iGWB are respectively stored in D:\Frontsave and E:\Backsave. 4)
Log
Log records the operations performed on the device through the maintenance console. Log is helpful in positioning faults. Log files are stored in D:\Other\Log. The system creates a log file every day. The generation date is used as the file name. The characters “log” are used as the extension of the file. Log file of the iGWB is stored for one month by default. After expiration, the log file will be deleted automatically. 5)
State query
The iGWB provides the state query function to facilitate routine maintenance, but the function is not very helpful in positioning faults. On the maintenance terminal, you can query the current running state of the iGWB. Table 4-5 lists the state available. Table 4-5 Common running state of the iGWB State
Description
Active and standby nodes
0 represents the active node, and 1 represents the standby node.
Heartbeat state
Heartbeat state is expressed as “n/m”, in which the denominator m indicates the total number of the heartbeat links and the numerator n indicates the number of the currently available heartbeat links. Usually two heartbeat links are configured, that is, m is equal to 2. If n is equal to 0, it indicates that the heartbeat is abnormal; otherwise, the heartbeat is normal. Note: If n is not equal to 0 and m is not equal to n, it indicates that part of the heartbeat links is faulty. To ensure the reliable running of the system, check the heartbeat links and recover the faulty link.
CPU usage
The iGWB supports displaying a maximum of two CPU usages. If only one CPU is configured, “-“ is displayed in the place of the second CPU usage.
Disk usage
The iGWB supports querying the total space and usable space of the front disk and the back disk, which is expressed as “n/m”. In “n/m”, the denominator m indicates the total space of the disk in MBs and the numerator n indicates the usable space of the disk in MBs.
4-9
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
State
Memory usage
Description The iGWB supports querying the usage of the physical memory, which is expressed as “n/m”. In “n/m”, the denominator m indicates the total size of the physical memory in MBs and the numerator n indicates the usable size of the physical memory in MBs.
To start the state query function, select [Operation/State Query] on the iGWB client. In the [State Query] window, click the Set Property icon. The [Setting Properties] dialog box is displayed. Set the [Save Status] to “Open”, and the status information will be saved in the StatsInfo.txt file on the installation directory of the maintenance terminal.
II. Information provided by the operating system The operating system provides the following information: 1)
IP address configuration
To obtain the IP address configuration, run #ipconfig -all. 2)
Network connection state
To obtain the current network connection state, run #netstat –na. To dump the outputs for future reference, run #netstat –na > 20031105.txt. It is recommended to name the dumping file the operation date. For example, “20031115” indicates that operation was performed on Nov 15th 2003. 3)
System log
To obtain the system log, start the Event Viewer and dump the Application Log and the System Log, as shown in Figure 4-2.
4-10
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
Figure 4-2 Dumping system log through Event Viewer 4)
Process running status
To check whether the processes of the iGWB are running, start the Windows Task Manager and click the [Processes] tab, as shown in Figure 4-3.
4-11
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
Figure 4-3 Checking process status with Windows Task Manager
Note: z
On a Windows-based platform, only the cls_proc.exe process is running at the inactive node, and the cls_proc.exe, knl_proc.exe, om_proc.exe, and ap_proc.exe processes are all running at the active node.
z
In addition to the query of the process existence, query several times and observe whether the process ID (PID) is changed. That is because the monitor process might frequently start the abnormal process in the event of abnormality, which causes the PID to increase even though the process exists.
4.4.2 Collection of Fault Positioning Information Collection of fault positioning information depends on the running of the system and the type of the fault. The following section presents the required information according to the type of the fault.
4-12
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
I. Interface communication fault This type of fault refers to the faults occurring to the interface between the SoftX3000 and the iGWB or the interface between the iGWB and the billing system. To remove such a fault, the following information should be provided: 1)
Parameter configuration file—igwb.ini
2)
All trace files
3)
IP address configuration (ipconfig/ifconfig) and network connection state (netstat) of the operating system
II. Bill exception This type of fault refers to the exceptional billing information found when you are viewing the bills or the billing complaints from subscribers. To remove such a fault, the following information should be provided: 1)
Parameter configuration file—igwb.ini
2)
Bill format configuration files (all files in \config\format of the installation directory)
3)
Original and final bill files containing the exceptional billing information
III. Start failure This type of fault refers to the various exceptions occurring to the start process of the iGWB application. To remove such a fault, the following information should be provided: 1)
Parameter configuration file—igwb.ini
2)
Bill format configuration files (all files in \config\format of the installation directory)
3)
All trace files
4)
IP address configuration (ifconfig/ipconfig) of the operating system
IV. Hardware fault Provisioning of the hardware fault positioning system depends on the log function of the operating system. It is required to dump the Application Log and the System Log in the Event Viewer and observe whether the hard disk status indicator on the hard disk array is normal. If the hard disk status indicator is red, it indicates that the hard disk is damaged.
4.4.3 Common Trace Information and Related Maintenance During the iGWB is running, some significant running information and fault information is recorded in the trace files in C:\igwb\Trace. The common trace information and the related maintenance measures are presented as follows:

User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
V. Usable back disk space insufficient for the minimum switchover space Open
the
C:\igwb\Config\igwb.ini
file.
Check
the
BackSaveRootDir
and
MinDiskHandoverRoom configuration parameters under the DiskFile configuration item. Confirm the disk storing the final bills (back disk bills) and the size of the minimum switchover space. Check the available space of the corresponding disk. If the available disk

VI. Access point type, access point type being %d Open the C:\igwb\Config\igwb.ini file. Check whether the APType parameter under the AccessPointN configuration item is correct. If not correct, correct the setting of the parameter. AccessPointN is the parameter related to a specific access point, in which N is the ID of the access point in the range of 1 to m and m is the value of the APCount parameter under the Common item. APType refers to the type of the access point which must be entered correctly. The value 0 represents the C&C08 switch provided by Huawei. The value 1 represents a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) product. The value 2 represents a signaling transfer point (STP). The value 3 represents a General Packet Radio Service (GPRS) product. The value 4 represents a Wideband Code Division Multiple Access (WCDMA) product. The value 5 represents a softswitch product.
VII. Failure of reading IP address from MML server (default value %s) Open the C:\igwb\Config\igwb.ini file. Check whether the LocalIpToMMLClient parameter under the MML configuration item is correct. If not correct, correct the setting of the parameter. LocalIpToMMLClient refers to the local IP address of the MML server for the connection to the MML client (the iGWB client), that is, the IP address for the iGWB to connect the network management system.
VIII. Error code %d returned in socket registration when connecting kernel process Probably the kernel process is not running. To check whether the kernel is running, press to display the [Windows Task Manager] window, and click the
4-15
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
[Processes] tab to see whether the kernel process exists. If the process does not exist, it is recommended to restart the iGWB server.
IX. Kernel process not running For the cause and solution, refer to the problem 8.
X. Failure of opening listening port (IP = %s, Port = %d) with error code %d Open the C:\igwb\Config\igwb.ini file. Check whether the IP address and the port number of the MML server under the MML configuration item are correct. If not, correct the settings. LocalIpToMMLClient refers to the local IP address of the MML server for the connection to the MML client (the iGWB client), that is, the IP address for the iGWB to connect the network management system. LocalPortToCM refers to the MML maintenance port of the MML server. It takes the value of 6000. LocalPortToAR refers to the MML alarm report port of the MML server. It takes the value of 6001. LocalPortToRD refers to the MML debugging port of the MML server. It takes the value of 6007.
XI. Activation failure of asynchronous resource (resource name %s and resource type %d) The asynchronous resource refers to the knl_proc.exe process. In this case, open the trace\knl_proc_trace.txt file to position the failure. In addition, an activation failure of the knl_proc.exe process might be caused by its sub-processes (ap_proc.exe and om_proc.exe), so open the ap_proc_trace.txt and om_proc_trace.txt files for further positioning purposes. For the specific positioning methods, refer to the problems 1 to 10.
XII. Dual-system activation failure Dual-system activation failure is caused by an activation failure of the asynchronous resource. For the specific methods for positioning an activation failure of the asynchronous resource, refer to the problem 11.
XIII. Unidentified heartbeat type (%s) Open the C:\igwb\Config\igwb.ini file. Check whether the Type parameter under the LinkN configuration item is correct. If not, correct the setting of the parameter.
4-16
User Manual U-SYS iGateway Bill
Chapter 4 System Maintenance
The Type parameter refers to the type of the heartbeat link. It can be set only to “UDP” or “COM”. UDP represents a private network link. COM represents a serial port link. Any other settings are incorrect.
XIV. Failure of creating heartbeat link %d (heartbeat name %s and heartbeat type %d) Check whether the heartbeat link configurations are correct based on heartbeat name or heartbeat type. If the heartbeat type is UDP, the LocalIp and PeerIp parameters must be correctly configured. If the heartbeat type is COM, the Port parameter must be correctly configured. Such an error is probably caused by the configuration of an inexistent local IP address or port number.
XV. Interruption of heartbeat link %d (heartbeat name %s and heartbeat type %d) According to heartbeat name or heartbeat type, check whether the cable connection of the network port or serial port used to transmit heartbeat between the dual systems is normal, whether the IP address setting is correct, and whether the peer end is running. Such an error occurs probably because the peer is not running.
XVI. Starting to perform failover operation (switchover cause %d) This piece of information indicates that because the local end of the iGWB becomes faulty, it must be switched to the peer. Table 4-6 lists the switchover cause codes. Table 4-6 Switchover cause table Switchover cause code
Explanation
0
Failed to write file, which is probably caused by insufficient disk space.
1
Insufficient front disk space, which means that the size of the available space of the disk storing the original bills is less than the minimum switchover space (400MB by default).
2
Insufficient back disk space, which means that the size of the available space of the disk storing the final bills is less than the minimum switchover space (400MB by default).
3
Asynchronous resource failure, which refers to the failure of the knl_proc process. For specific troubleshooting methods, refer to the problem 11 earlier in the trace description.
4
Activation failure of the cls_proc.exe process, which is probably caused by an asynchronous resource activation failure or resource creation failure. Such a failure is positioned according to the specific trace information.

5
Resource failure. Resource failure includes virtual IP resource failure, volume resource failure, and service failure. Refer to the trace information for the further troubleshooting.
6
Damaged hard disk of the array. Replace the damaged disk.
XVII. Failure of failover operation Such a fault is probably caused by the faultiness of the local iGWB, in which the local iGWB detects the interruption of all heartbeats. In addition, such a fault occurs because of an activation failure when the peer attempts to activate itself upon receipt of the failover command. Such a fault is generated by the local iGWB. In this case, confirm that the peer is running, and remove the faults at the peer.
XVIII. Operation failure at failover response end Such a fault is caused when the local iGWB attempts to activate itself upon receipt of the failover command but fails. Check other specific trace information to position the activation failure.
XIX. Starting to perform handover operation Generation of this piece of information is caused by the following: 1)
The active server is being started.
2)
The peer iGWB is faulty, and the local end is deactivated.
3)
The local iGWB receives a manual switchover command from the client.
XX. Multiple failed activation attempts at local node and never activatable unless heartbeat is interrupted The local end continuously performs activation attempts (three times by default), but all fail. In this case, the local end stops the activation operation, and enters the FAILDOWN state. After one hour, the local end restores to the normal state, and starts the activation operation again. The local end repeats the same until the heartbeat links are restored to be normal.

When logging in to the bill console, you enter the correct username and password, but the system prompts “Connect Server Failed, Relogin?” It indicates that the iGWB is not running or is running abnormally. In this case, start the iGWB and log in again. 2)
Network failure
If a network failure occurs when you are operating the bill console, for example, viewing the bills or logs, the system prompts the corresponding message as shown in Figure 4-4. In this case, check whether the network is normal, or exit the client and re-connect again.
Figure 4-4 Prompt message of bill console in case of a network failure 3)
iGWB switchover
If an iGWB switchover happens when you are operating the bill console, the connection between the client and the server is interrupted. After the switchover, log in again.
II. Dual-system switchover If the iGWB is backing up the bill files when a dual-system switchover happens, the bills stop being backed up. The on-going backup will not continue after the other iGWB starts. Because the bill files are stored in the respective hard disk arrays of the active and standby iGWBs, the bill data will be distributed after the switchover. To avoid that, insert a new backup medium into the switched iGWB server and back up the bill files that are generated after the switchover. The bills generated before the switchover continues to be backed up after the switched iGWB server restarts. It is recommended to number the backup media in the order of the generation of the bills for identification purposes. If the stopped backup in the dual-system switchover is an automatic backup, the automatic backup can also be performed correctly in future. If it is a manual backup, the appropriate processing measures must be taken to continue the backup.
III. Incorrect username or password When you are attempting to log in to the bill console, the system prompts “Log Failed: Password Error”. In this case, the entered password is not correct. Enter the correct password.

When you are attempting to log in to the bill console, the system prompts “Log Failed: Account does not exist”. In this case, the entered username is not correct. Enter the correct username.
IV. iGWB shutdown Select [Start/Programs/iGateway Bill V200 Server/Stop iGateway Bill] on the active server, and the bulb of the standby server is not on. Restart the active server, but the bulb of the standby server is still off in five minutes. This is caused by incorrect operation steps. Before stopping the iGWB, stop the "Process Watch Dog Service” first. For details, see 4.3.2 2)

Appendix A iGWB Configuration Instance
Appendix A iGWB Configuration Instance You can configure the iGWB running mode to single host or dual system according to actual requirements. This chapter details the instances for these two configuration modes.
Caution: z
We should not manually set the virtual IP addresses of iGWB network adapters directly, which will cause iGWB software start unsuccessfully;
z
Configure the virtual IP address of the iGWB network adapter indirectly by configuring the igwb.ini file. For details about igwb.ini configuration, see 2.5.2 Modifying Server Software Settings.
z
The iGWB reads the igwb.ini file to obtain the information about the virtual IP address to be set, and automatically adds the virtual IP address to the iGWB network adapter accordingly.
A.1 Configuration for Single-host Mode This section shows the instance of setting the single-host mode from the aspects of networking, IP address setting rules and configuration file contents.

Appendix B Software Directory Description
Path
Description The final CDRs of iGWB are stored in the e:\backsave directory, usually in two copies. 1) The CDRs are stored in the directory of e:\backsave\access point\path\date, that is, stored by access point, by path, and then by date.
e:\backsave
z
2) The copies are stored in the directory of e:\backsave\Second\point\path, in a slightly different structure. That is, the copies are no longer stored by date. This directory is usually open to the billing center to get CDRs, and the billing center is required to delete its obtained CDRs in real time. That’s why there are usually no accumulated CDRs in this directory.
Main files
Table B-4 Main files Name and path
Description SoftX3000 sends a 156-byte CDR to iGWB regularly. Then, iGWB fills the content of the received CDR into the original CDR file till the file size exceeds the specified size, usually 3M. Afterwards, the preceding operations repeat for different original CDR files.
d:\frontsave\access point\path\date\b?.bil
The name of the original CDR file is b?.bil. Herein, the question mark ? is the serial number of the CDR, numbered from 0000000001 to 9999999999 by access point. For example, the file b0000000009.bil in the d:\frontsave\X3KF\20040314 directory is the ninth original CDR file generated by the access point X3KF on Mar 14, 2004. iGWB converts the received CDR information and fill it into the final CDR file while generating the original CDR, till the file size exceeds the specified size, usually 1M. Afterwards, the preceding operations repeat for different original CDR files.
e:\backsave\access point\path\date\ b?.dat
The name of the original CDR file is b?.dat. Herein, the question mark ? is the serial number of the CDR, numbered from 00000001 to 99999999 by path. For example, the file b00000009.dat in the e:\backsave\X3KF\detail\20040314 directory is the ninth detailed final CDR file generated by the access point X3KF on Mar 14, 2004. Note: 1) For different conversion types, the generated CDR files are different. 2) In the CDR storage directory, the “access point name” comes from the [ AccessPoint%d ] /APName setting in the parameter configuration file igwb.ini.
